Which of the following steps cannot occur in the rock cycle?igneous to sedimentmagma to sedimentary rockmetamorphic to magmasedimentary to metamorphic

The step that cannot occur in the rock cycle is "magma to sedimentary rock".

Here's why:

1. Igneous to Sediment: This is a possible step. Igneous rocks can be broken down through weathering and erosion into smaller particles, or sediments.

2. Magma to Sedimentary Rock: This is not a possible step. Magma, when cooled, forms igneous rocks, not sedimentary rocks. Sedimentary rocks are formed from the accumulation of sediments, which are often the result of weathering and erosion of existing rocks.

3. Metamorphic to Magma: This is a possible step. Metamorphic rocks can be melted under extreme heat and pressure to become magma.

4. Sedimentary to Metamorphic: This is a possible step. Sedimentary rocks can be subjected to extreme heat and pressure to form metamorphic rocks.
